Dispensing device for collapsible tubes



Feb. 25, 1936. F, POULIN DISPENSING DEVICE FOR COLLAPSIBLE TUBES Filed Oct. 3, 1935 Patented Feb. 25, 1936 UNITED STATES PATENT OFFICE DISPENSING DEVICE FOR COLLAPSIBLE TUBES Application October 3, 1935, Serial No. 43,401 In Canada September 3, 1935 2 Claims.

This invention relates to a dispensing device for collapsible tubes, the general object of the invention being to provide a cap for the tube rotatably mounted thereon and a closure member and 5 means for moving said member to closing and opening position by rotary movement of the cap.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts to be hereinafter fully described, illustrated in the accompanying drawing and specifically pointed out in the appended claims.

In describing the invention in detail, reference will be had to the accompanying drawing wherein like characters denote like or corresponding parts throughout the several views, and in which:-

Figure l is a view of a collapsible tube constructed in accordance with the present invention.

Figure 2 is a vertical sectional view through the upper portion of the tube shown in Figure 1 with the closure in closing position.

Figure 3 is a similar view but with the closure in open position.

Figure 4 is a top plan view of the tube with the other parts omitted.

Figure 5 is a view of the closure member.

In this drawing, the numeral l indicates the usual collapsible tube which is provided with the cylindrical neck 2 having a flange 3 thereon. The cap is shown at 4 and the lower end of the cap is reduced in thickness so that it can be upset over the flange as shown at 5 to rotatably connect the cap with the tube for making the cap a permanent part of the tube. The top of the neck 2 is formed with a circular opening 6 having oppositely arranged notches 7 in its walls and the cap having a substantially conical top provided with a discharge opening 8 and the cap is internally threaded as shown at 9. The closure member is shown at l and includes the frusto-conical upper end I I closing the opening 8 when the closure is in raised position, the stem l2, the cross bar l3 having its ends threaded as shown at M 45 and the narrow substantially rectangular part l for fitting in the notches 1 and across the circular opening 6 to prevent rotary movement of the closure member and also to prevent the closure member from entirely closing the opening 6. The threads l4 engage the threaded portion 9 of the cap so that by rotating the cap in one direction the closure member will move upwardly until the part H closes the opening 8 and then no paste or other contents of the tube can escape. By turning the cap in an opposite direction the closure member is moved downwardly and thus by squeezing upon the tube some of the contents will flow by the parts l3 and I5 and pass the part II and then flow out of the opening 8 which may be of any suitable form.

From the foregoing it will be seen that I have provided a cap which forms a permanent part of the container and a closure member which is moved to open and closed position by rotary movement of the cap, the parts being but three in number and inexpensive to manufacture and assemble so that the entire device can be manufactured to sell at low cost.

It is thought from the foregoing description that the advantages and novel features of the invention will be readily apparent.

It is to be understood that changes may be made in the construction and in the combination and arrangement of the several parts provided that such changes fall within the scope of the appended claims.

What is claimed is:-

1. In a collapsible tube having an opening in its top, a cap rotatably connected with the top and having an opening in its top, a longitudinally movable closure member in the cap having a part for closing the opening in the cap and means whereby rotary movement of the cap in one direction will move the closure member to closing position and rotary movement in the opposite direction will move said closure member to open piece having threads at its ends for engaging the threads of the cap and a thin depending portion passing across the opening in the top of the tube and into the notches for preventing rotary movement of the closure member while permit- FRANCOIS POULIN.
